SPECIFICATION forming part oi Letters Patent 510,541,821, dated July 2, 1895.

Application led December 4, 1894. Serial No. 530,801'- (No model To all whom it' may concern:

Be it known that 1, ISAAC BABBrrT, a citi- Zen of the United States, residing at Princeton, in the county of Gibson and State of Indiana, have invented a new and useful Uhuru, of which the following is a specification.

The invention relates toimprovements in churns.

The object of the present invention is to improve the constructionof churns, and to provide an apparatus which will enablebut- Ater to be rapidly produced at the expenditure of a minimum amount of labor.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanyingdrawings, and pointed out in the claims hereto appended.

In the drawings, Figure lis an elevation of a churning apparatus, constructed in accordance with this invention. longitudinal sectional view. Fig. 3 is a hori- Zontalsectional view of the churn body, illustrating the construction of the rotary air distributer. Fig. 4 is a detail sectional view, illustrating the construction of the air distributer.

Like numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designates a churn body, preferably of cylindrical form, provided with a cover 2, and having removably stepped in it a vertically disposed hollow stem 3, which conducts air to a rotary distributer 4, located at the bottom of the churn body. The rotary distributer consists of a sleeve 5 mounted on the lower end of the stem 3, between an annular shoulder 6 and a cap 7, and a series of radial tubular arms provided at their outer terminals with laterally disposed openings 8, whereby the distributer is caused to rotate when air passes through the tubular arms. The laterally disposed openings are preferably formed by curving the outer terminals of the tubular arms slightly, but any similar construction may be employed. The lower end of the stem is provided with an opening located within the rotary sleeve, and distributing air to the tubular arms. The cap 7 isinteriorly threaded and tits on thelower end ofthe stem, which has a solid portion, and which is also threaded,

Fig. 2 isa verticalA and which is provided with a threaded socket receiving a screw 9, for assisting in securing the cap on the lower end of the stem. The cap fits over thelowerend of the rotary sleeve, and the upper end of the latter receives the annular shoulder, thereby making a close joint or connection. On the stem is secured a conical shield 10, located a short distance below the cover 2 of the churn body, and adapted to prevent cream from splashing out ot the churn body, when. it is agitated by the introduction of air under pressure. After passing through the cream the airis permitted to escape through a vertical tube 1l, extend ing from the shield l0 through the cover 2. The cover is provided with a perforation to receive the tube ll. The shield has a similar perforation, and in practice the shield will preferably be constructed of two sections, clamped or otherwise secured to the vertical stem 3, but any form of attachment may be employed. The air for` agitating the contents of' the churn body for'the production'of butter is obtained from two single cylinder air pumps 12 of ordinary construction having a common discharge tube 13, connected with a depending tube 14 of a water containing vessel 15, through which the air is forced for the purn pose of cleaning the same. The vessel 15 is provided at its top with a filling opening, threadedand receiving a removable screw plug 16, adapted to be unscrewed to permit water to be introduced into the vessel 15. The' depending tube 14E extends nearly to the bottom of the water containing vessel 15, and the air, after passing through the water, enters a supply pipe 17, which conducts it to the vertical stem 3 of the churn body.

In order to raise the air to the proper temperature, which is preferably 62 to 65 Fahrenheit, a heating coil 18 is employed, and is detachably coupled to the supply tube 17 at an intermediate point of the same. The coil 1S is arranged within a metal chimney 19 of a lamp 20, and the temperature is indicated by a thermometer 21 located at the top of the tubular stem 3. The thermometer is detachably mounted on, and has its mercury bulb located within a T-coupling 22, being provided with a screw-plug, and rubber washer for making a tight joint. By this construc- IOO tion the temperature ofthe air may be readily controlled.' The air introduced in this manner into the contents of the churn body is capable of producing butter, and, after the operation of churning has been completed, the liquid is drawn oft at the bottom of the body through a faucet 23, and the butter, which collects in globular form, may be readily removed by means ot' a Wire screen or basket (not shown), previously placed in the churn body.

After the operation of churning has been completed, the pipes and tubesare washed by the Water contained Within the vessel l5, which is forced through the pipes and tubing by the air pumps. A water pipe 24 communicates with the bottom of the receptacle l5, and with the supply pipe or tube 17, and at the point of juncture with the latter is located a three way cock 25, adapted to close the adjacent end of the water pipe or tube 24, during the operation of churning, and to close the supply tube or pipe between it and the Vessel l5, to cause thefair to force the water into the Water tube into the supply tube to the stem, and rotary air distributer. Vhen the supply tube is closed between the three- Way cock and the receptacle communication is established between the Water pipe and the rest of the supply pipe or tube.

The apparatus may be readily taken apart for storing and may be quickly assembled for use. Couplings 26 permitthe coil to be readily removed and assembled, and the other parts may be readily separated.

It will be seen that the apparatus for churning is simple and comparatively inexpensive in construction, capable of easy operation,

vand adapted to effect a rapid production of butter. It will also be seen that after the the Water employed for cleaningandwashing the air. tube.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

l. In an apparatus for churning, the combination of a churn body, an air distributer arranged therein, a supply pipe communicatling with the air distributer at one end, a Water containing receptacle located at the other end of the supply pipe, a tube depending from the top ot' the receptacle, means for introducing air under pressureinto the depending tube, a Water pipe extending from the bottom of the receptacle to the supply'pipe, and a cock located at the point of connection of the water pipe to the supply pipe for closing the former, and also for establishing a communication between the Water pipe and the supply pipe, whereby water from the receptacle may be forced throughthe supply pipe, substantially as described.

2. In an apparatus for churning, the combination of a churn body, an air distributer arranged therein, a supply pipe communicating With the air distributer, a Water receptalcle located atl one end of` thesupply pipe, a..

pump connected with the receptacle, the water pipe extending from the receptacle tothe supply pipe, the coil connected with thesup.- ply pipe, and means for heating the coil, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiiXed my signature in the presence of two witnesses.
